The term vital stain is used by some authors to refer to an intravital stain, and by others interchangeably with a supravital stain, the core concept being that the cell being examined is still alive. In a more strict sense, the term vital staining has a meaning contrasting with supravital staining.
Thus a supravital stain may have a greater toxicity, as only a few cells need to survive it a short while. The term "vital stain" is used by some authors to refer specifically to an intravital stain, and by others interchangeably with a supravital stain, the core concept being that the cell being examined is still alive. As the cells are alive ...
Drawing by Camillo Golgi of a hippocampus stained with the silver nitrate method Drawing of a Purkinje cell in the cerebellum cortex done by Santiago Ramón y Cajal, clearly demonstrating the power of Golgi's staining method to reveal fine detail. Golgi's method is a silver staining technique that is used to visualize nervous tissue under light ...
In vivo staining (also called vital staining or intravital staining) is the process of dyeing living tissues. By causing certain cells or structures to take on contrasting colours, their form or position within a cell or tissue can be readily seen and studied. The usual purpose is to reveal cytological details that might otherwise not be ...
The term is still used today, but its meaning has changed over the years, and is used inconsistently in present-day literature. Although RES is commonly associated exclusively with macrophages, recent research has revealed that the cells that accumulate intravenously administered vital stain belong to a highly specialised group of cells called ...
This plated viability assay measures various yeast viability though a method called "frogging". The research is completed through drop-inoculation techniques. Research has since been conducted on "tadpoling", which is a variation of "frogging" that is completed by keeping the test cells diluted in liquid throughout their examination. [1]
Health psychology is a discipline that understands the psychological, behavioral, and cultural aspects that affect the physical health and illnesses within individuals. A psychologists with the focus of health psychology would have a biopsychosocial model approach with patients.
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.
